Built not to break
A module that floats
Inside a hollow case, the module (the heart of the watch) seems to float, so knocks from outside are softened before they reach it. The idea came from watching children play with a rubber ball.
2-year warranty
Every G-SHOCK watch from Watch Direct comes with a 2-year warranty from Shriro Australia, Casio’s exclusive Australian distributor.
Watch Direct is an authorised G-SHOCK retailer, trading since 2011.
About G-SHOCK
G-SHOCK began with a dropped watch. Casio designer Kikuo Ibe saw a watch break when it fell, and proposed “a durable watch that would not break even if dropped”. The project set itself the “Triple 10” goal: survive a 10-metre drop, resist water to 10 bar and run for 10 years on one battery. The first G-SHOCK, the DW-5000C, arrived in 1983.
